. ELEVATORSAEETY DEVICE.

To all whom may concern:

Be it known that I, GEORGE S. iMoGYoRs,

a subject of the King of Hungary, residingV 'at Dayton, in the county ofMontgomery and State of Ohio, have invented certain new and usefulImprovements in `Elevator Safety Devices, of which the following isaspecil ication This invention relates to certain new and usefulimprovements 1n elevator-.safety de- Y vices. f

The primaryr object'of this-invention is to provide means carried by anelevator car automatically actuated upon a breaking of the hoistingcable for the purpose: of'lockingly tents of the car.

Ararat-,r Object of the inveaaon'is the provision of oppositely slidablespringpressedbolts carried by an elevator vcar and being retainedretracted by means -Of engaging rods when the hoisting cableissupporting the car, the said rods being' automatically released upona-severing of the-cable, and; 'whereby individual kprojecting means lfor the said Vbolts position thelatter in locking engagement with thesidebeams of the shaft.

vWith thesey general objects in view and others that will appearas thenaturewof the invention isloetter understood, vthe same Vconsists in thenovel combinationfand arrangement of, partsjhereinafter 4more fully de-Vscribed, 'illustrated in the vaccompanying side beams of the shaft.Fig. 2 is av vertical drawings, and pointed out in the'appe'nded claim.f

Fig. 3 is aview similar to Fig. 1, but lwith the elements in their locked positionas assumed when the cable is broken.

vthe top thereof.V the opposite-outer ends 15 of .which are adapted forsliding'upon the guide strips 11. The bottom 16 of the car is providedwith a similar transversely positioned beam 17 upon the lower sidethereof,

and its opposite ends 18 arearranged to slidably-engage Athe strips 11similar to the arrangement I described in connection with the upperbeam14E. l

The car bottom 16 is provided at opposite points withV chambers 18, eachof the same having a right-angular form of locking bolt 19 mountedtherein, the engaging arm 20 of the Vsaid bolt kbeing slidablypositioned througha slot A21A opening at the adjacent outer edge 'of thevcar'bottom andv in alinement with the adiacent guide strip 11. Aspindle 22 is provided upon the bolt 19 eX- tending inwardly inalinement with the locking arm 2O thereof andfis slidably journaled inaperforated bracket 23 within the chamber, while an expansion spring 24encircles the said spindle and bears between the lockingkbolt andthebracket23. A vertical slidable rod 25 is slidably mounted at each sideof the car through vertical alining perforations 26 and 27 in the upperand lower beams-14 and 16 respec- .such bolt,y when the `'bolt` isretracted. A resetting lever 29 is provided for each of the bolts 19,the said levers being pivoted as at 30' to the adjacent' portion of thecar and having a pivotal link connector 31 between the lower end of thelever and the projecting arm 32 of the locking bolt. B v thisconstruction, it'will bek seen that when the rod 29 is engaged withinthe-perforation 28 of its respective locking bolt, the said bolt will beretained retracted and at which time its spring k24 will be compressed,while an upward movement of the rod 25 will release the locking bolt,thus allowing its spring 24 to automatically project the bolt, andwhereby the same will engage the adjacent one of the rsaid guide' stripnotches 12. By outwardly moving the lever 29, the spring will beagaincompressed and the perforation of the boltbrought into alinementWith-the.Av e. adjacent rod Which may "be` positioned .therethrough bythe means hereinafterset forth.

with upright brackets 33V in the bifurcated tops 34 on vwhich oppositelyiprojecting'le- 1- vers 35 are freely piyoted, While the Vopposite outerendsiof the levers 35Y are provided with' longitudinal slots 36' hav-ingtransverse bolts mounted therein which areV secured to theV upperf freeends vof. the rods 25. The
